SNAP-BUTTON.

SPECIFICATION forming part of Letters Patent No. 777,043, dated December 6, 1904.

Application led April 22, 1904. Serial NoK 204,351. (No model.)

To (/,ZZ 1,071,071?, it nan/y concern.:

Be it known that l, Jol-[N MGLEAN, ot' Newark, in the county of Essex, in the State of' New Jersey, have invented new and use't'ul lmprovements in Snap-Buttons, of which the iiollowing', taken in connection with the accompanying drawings, is a t'ull, clear, and exact description.

This invention relates to improvements in snappingl buttons in which a kinked spring-leal.g is mounted upon a thin sheet-metal sounding board or shell and adapted to be operated for producing' a snapping' sound.

My object is to mount one end oi' the buckled spring-leaf upon the convex base oi a sheetmetal cup having' a cap closing its open end for forming' an interior chamber, so as to reverberate the sound produced by the operation of the snapping` spring'.

Another object is to provide the base with suitable parallel transverse bars arranged in different planes one in advance oitl the other and to insert the end of the spring-leatl under one Olil the bars and over the other, whereby the spring-leal is held in place andpermits its free end to be sprung' by hand a limited distance for producing' the snapping' etlect without cutting' away the portion of the base underl ying' the free end et' the snapping' spring'.

In the drawings, Figure 1 is an inverted perspective view o1 my improved snapping button. Figs. 2 and 3 are sectional views taken. respectively, onlinesZQand 3 3, F 1. Figs. Il, 5, and 6 are perspective views showing, respectively, the cap or cover, the sheetmetal cup or shell, and the spring' snapping' leaf.

Similar reference characters indicate corresponding parts in all the views.

ln carryingout the object stated I provide a sheet-metal cup 1 with a convex bottom 2 and i'laring sides 3, the open side of the cup being closed by a suitable sheet-metal cap Ll, having' a covering' 5. of celluloid or other suitable material, which is adapted to receive a print or other ornamentation. This cover constitutes the exposed i'ace or iront oit' the button and is provided with an annular liange 6, while the' marginal edges oi' the covering' 5 are turned inwardly around the edg'es of the iiange G and are impinged between said 'Flange G and the Haring' sides 3 of the shell l. In other words, the flange 6, with the covering' thereon, is crimped over the adjacent edges of the flaring sides 3. thereby locking the two circular parts together.

The base 2 oi the cup 1 is formed with a transverse slot 7 and with substantially parallel slits 8, the stock between the slits being' depressed inwardly to form a transverse bar 9 and a slot 10, the bar 9 having' its ends integral with the base 2 at opposite ends ot' the slot 10. These slots 7 and l() are disposed one in advance et' the other, thus forming' a second transverse bar 1l, running' parallel with and between the slots 7 and 10. These bars 9 and 10 are also arrang'ed one in advance oil the other, but in dilierent planes. for receiving' and retaining' a spring snapping' leat' 12, which is buckled centrally at 13. This lever 12 is inserted through the slot 7 and under the transverse bar 1.1, but over the transverse bar 9. so that its inner end lies within and close to the inner 'face of the convex bottom 2. while its outer free end eX- tends outwardly through the slot 7 and lies along' the outer convex face et' the bottom 2, so that the free edge of the snapping spring' is some distance from the adjacent outer't'ace ot' the bottom 2 to allow a sui'licient movement ol said t'ree edge to produce the snapping' e'tlect. This 'free edge of the snappingl leaf also lies in a plane substantially coincident with the periphery of the cup.

let will be seen upon reference to Fig'. 2 that the edge ot' the slot 7 opposite the bar 11 'lorms a fulcrum iior the snapping' spring 12, and in this ligure and also in Fig. 3 it will be seen that a space is le't't between the buckled portion 13 of the snapping leaf and the inner lface of the bar .111 to permit this part of the snapping-lettil to be sprung' outwardly as the free end of the lever is depressed, thus producing' the snapping' effect.

In order to make a more ellicient sounding'- board of the cap it is generally provided with an additional slot or opening' la beneath the iree end of the spring-leaf 12, which permits the escape of the reverberated soundwaves.

IOO

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1.` A snapping'button comprising a shell having slits spaced apart and the intervening' portion depressed to form a bar, and a spring snapping leaf having one end inserted through the slits and across the bar.

2. A snapping button comprising a sheetmetal shell having a portion thereof partially severed and depressed and forming a slot and an underlying bar united at its ends to the shell and a spring' snapping leaf having one end inserted across the slot between the bar and adjacent parts of the shell.

3. A snapping button comprising a sheetmetal shell having substantially parallel slots, a bar secured at its ends to the shell at opposite ends of one of the slots, and a spring snapping leaf inserted through the other slot and between said bar and adjacent portions of the shell.

4. A snapping button comprising a shell', substantially parallel bars united to the shell one in advance of the other but in different planes, and a spring snapping leaf having one lnd inserted under one bar and over the other 5. A snapping-button comprising a sheetmetal cup and a cap for its open side, the base of the cup being formed with bars arranged one in advance of the other but in different planes` and a spring snapping leaf inserted under one bar and over the other.

In witness whereof I have hereunto set my hand this 19th day of April, 1904.

JOHN MCLEAN.
